CARBURETER.

SPECIFICATION forming part of Letters Patent No. 714,414, dated November 25, 1902.

Application iled October 30I 1901. Serial No. 80.4.93. (No model.)

following is a specification.

This invention relates to apparatus for the production of illuminating-gas from gasolene or analogous hydrocarbons; and the invention has for its object to increase the efficiency of this type of carbureters both in the q11ality of carbureted air produced and in the economy in the production of the same.

The nature of the invention is fully disclosed in the description and claims following, reference being had tothe accompanying drawings, forming a part of the specification, in whichx Figure l is a diagrammatic view of apparatus embodying my invention. Fig. 2 is a section of the sprayer, and Fig. 3 is a section of the drier.

In the drawings, A designates a water-tank or cistern, in which is mounted a bell B in the usual way. In the bottom of this tank is a carbureter C, communicating with the 'interior of the bell b v a vertical air-pipe C.

' Air is forced into this bell through a looped pipe D, communicating with a blower (not shown) either directly or through an airchamber E, which may connect with the pipe D by pipes E and E2. By means of cocks D and E3 the air may be conveyed through or around the air-chamber, as desired. The purpose of this ainchamber is to take and absorb the pulsations of the blower, which otherwise are communicated to the service-mains and cause more or less iiicker in the lights.

The gasolene or other suitable hydrocarbon is contained in bulk in a reservoir F, the bottom of which is lower than the bottom of the carburetor, but its top is higher. A pipe G'leads from the lower part of the carburetor to the lower part of the reservoir and is provided with a suitable stop-cock Gr', opened and closed by a long-stemmed wrench G2. The upper parts of the carbureter and reservoir are connected by a pipe H.

I is a supply-pipe for the reservoir.

J is a pump which is provided with a pair of suction-pipes K and K', provided with suitable cocks K2 and K2, respectively. The pipe K extends to the bottom of the reservoir and serves for drawing out the heavier and poorer gasolene,which naturally settles to the bottom of the reservoir. The other one terminates seine distance from the bottom and is used to supply a small tank L, placed high enough so that a part of its contents may iiow into a sprayer-tank M. A pipeN connects the pump with the tank L and is provided with a stopcock N'. A waste-pipe O also communicates with the pump and has a stop-cock O. y

When it is desired to pump out waste material, the cocks O and K2 are opened and the cocks N and K2 are closed.

From the sprayer-tank a pipe P leads tothe carburetor and serves as a conduit for the gas generated therein. To this pipe is connected a looped pipe Q, leading to -the opposite end of the tank and provided with a cock Q. By means of cocks P and P2 the gas may be passed directly into the tank or carried around it to the other end and enter through the spray-pipe R, connecting the chambers L and M.

S is a drain-pipe to carry the residuum of the sprayed gasolene down to the carburetor.

A simple form of spraying apparatus is shown in Fig. 2. In this the gasolene-pipe R projects through an elbow Q2 and inside the pipe Q. At the inner end of the pipe Q is set a cone T, whereby the commingled gas and gasolene are scattered in a fine spray inside the chamber M. By this means the carbureted air after leaving the carbureter may be still further enriched if it shall be found wanting ICO W, which is provided with a stop-cock W. A loop U2 connects the drier with the main, and by means of the cocks U' and W the carbureted air may be carried from the spraytank directly to the main or through the drier, as circumstances may require. The carbureted air passes to a gasometer X and thence to the outside or service main in the usual way.

The gasometer-bell may connect by a chain Y, passing over sheaves Z, with the lever of the stop-cock R', and thus the flow of gasolene through the spray-pipe be automatically shut off whenever the bell reaches a certain elevation.

The proper level of gasolene in the chamber L is ascertained by means of a gage-glass L'.

It will be observed that after gasolene has been pumped to the desired level in the receiving-chamber L and the various cocks have been properly adjusted the action of the apparatus is automatic, the blower supplying -air by which gasolene is vaporized in the carbureter and the spraying apparatus supplying new gasolene for what is consumed.

It is to be noticed that the construction is such that only good gasolene can be used in the carbureter, the heavy and gummy material all being drawn away from time to time from the bottom of the reservoir.

I have called the tank B a compressed-air tank and the tank E a pulsation-reducer, for such is its function. It is placed in the circuit between the source of supply of cornpressed air and the compressed air tank, though the connections are such that it may be cut out of this circuit.

I claimy l. In acarbureterspraying device, the combination of a tank with a pipe-opening therein at each end, a looped pipe about the same, a gas-supply opening into the pipe at one end and into the loop at the same end, said loop opening into the pipe which opens into the spraying device at the other end, a hydrocarbon-supply pipe opening into the second pipe which leads into the sprayer, and suitable valves whereby the gas can be passed through the loop and mingled with the hydrocarbon or can be passed directly into the sprayer.

2. In a machine for carbureting, The combination of a carbureter wit-h a reservoir for holding gasolene, arranged so as to extend vertically partly below and partly above the level of the carbureter, with pipes connecting the upper and lower parts of the carbureter and reservoir respectively, a sprayingchamber and a sprayer therefor, a receivingchamber to receive gasolene', and connections whereby the gasolene may Iiow thence into the spraying-chamber, pipes connecting the carbureter with the sprayer and the sprayer with the receiver for gasolene, and means for supplying said receiver from the reservoir substantially as set forth.

3. In a machine for carbureting, the cornbination with a carbureter and means for supplying air thereto under pressure, 'of a spray-- ing-chamber, a gasolene-receiver adjacent thereto and a connecting-pipe provided with spraying apparatus, a pipe leading from the bottom of the spraying-chamber to the carbureter, a pipe leading from the said chamber at a higher level to the carbureter, a pipe leading from said higher pipe around the spraying-chamber and connecting with the spray-pipe, and cocks to regulate the flow of gas and gasolene, whereby the gas from the carbureter may be conducted direct to the spraying-chamber, or through the sprayer in'to said chamber, and the surplus gasolene may be conducted to the carbureter, as described.

4. In a machine for oarbureting, the combination with a carbureter and means for supplying the same with air under pressure, of a reservoir for gasolene extending both above and below the levels of the top and bottom of the carbureter, pipes connecting the upper and lower portions of the carbureter and said reservoir, respectively, a stop-cock for the lower pipe, a pump provided with two suction-pipes, one extending to the vbottom of the reservoir and the other to some distance above said bottom, cocks therefor, a receiver for gasolene as pumped from the reservoir, a pipe connecting said receiver with the pump and a cock therefor, asprayer, and pipes connecting the receiver with the sprayer, and the sprayer with the carbureter, substantially as and for the purposes set forth.
